About 30 penguins were dropped at the centre annually, but it was the first from Remuera.
Ms MacDonald said today that the penguin had been doing well under her care.
On SPCA advice the penguin's rescuers had fed the bird a bowl of mushed up sardines, however "unfortunately sardines don't cut the mustard,'' Ms MacDonald said. Penguins weren't prone to eating food they hadn't caught so, it was being fed a critical care diet through a tube.
When the penguin's strength is up he would be placed in an enclosure with a female penguin recovering from sun bleaching, Ms MacDonald said.
However, she doubted any romance would blossom. "They're both from different coasts so they won't be together forever.''
Neither penguin had, or likely would, be named, Ms MacDonald said. "We deal with 5000 birds a year, can you imagine naming them all.''
A vet would check the male penguin tomorrow, she said.
